Embodiment Construction

[0013] The implementation of the image processing-based electric energy meter reading recognition device of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] The working principle of the electric energy meter is as follows: when the electric energy meter is connected to the circuit under test, an alternating current flows in the current coil and the voltage coil, and the two alternating currents generate alternating magnetic flux in their iron cores respectively. The alternating magnetic flux passes through the aluminum disc and induces an eddy current in the aluminum disc; the eddy current is subjected to force in the magnetic field, so that the aluminum disc obtains torque (active torque) and rotates. The greater the power consumed by the load, the greater the current passing through the current coil, the greater the eddy current induced in the aluminum disc, and the greater the torque that makes the aluminum disc ro...

Abstract

The invention relates to an electric energy meter reading recognition apparatus based on image processing. The apparatus comprises a CCD camera, an image processor, an image recognizer and a wireless communication interface; the CCD camera is used for shooting the electric energy meter to obtain an electric energy meter; the image preprocessor is connected with the CCD camera and used for preprocessing the electric energy meter to obtain a preprocessed electric energy meter; the image recognizer is connected with the image preprocessor and used for performing reading recognition on the preprocessed electric energy meter image; the wireless communication interface is connected with the image recognizer to wireless transmit the electric energy meter reading to an upper computer. According to the electric energy meter reading recognition apparatus based on image processing, the electric energy meter can be automatically read without modification, and the accuracy of reading can be guaranteed even in foggy weather.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to an image processing-based electric energy meter reading recognition device. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric watt-hour meter, a fire meter, and a kilowatt-hour meter. [0003] Energy meters can be classified as follows: by use: active energy meters, reactive energy meters, maximum demand meters, standard energy meters, multi-rate time-sharing energy meters, prepaid energy meters (coin-operated, magnetic card, electricity card type), power loss meter, according to the working principle: induction type (mechanical type), static type (electronic type), electromechanical integrated type (hybrid type); according to the nature of the power supply: AC meter, DC meter; according to the structure: overall type, split type; according to the access phase line: single-phase, three-phase th...
